Sidera Lodoicea
Sidera Lodoicea is the name given by the astronomer Giovanni Domenico Cassini to the four moons of Saturn discovered by him in the years 1671, 1672, and 1684 and published in his ''Découverte de deux nouvelles planètes autour de Saturne'' in 1673 and in the ''Journal des sçavans'' in 1686. These satellites are today known by the following names, given in 1847: * Iapetus or Saturn VIII, discovered October 25, 1671 * Rhea or Saturn V, discovered December 23, 1672 * Tethys or Saturn III, discovered March 21, 1684 * Dione or Saturn IV, discovered March 21, 1684 The name ''Sidera Lodoicea'' means "Louisian Stars", from Latin ''sidus'' "star" and ''Lodoiceus'', a nonce adjective coined from ''Lodoicus'', one of several Latin forms of the French name ''Louis'' (reflecting an older form, ''Lodhuwig''). Cassini intended the name to honor King Louis XIV of France, who reigned from 1643 to 1715, and who was Cassini's benefactor as patron of the Paris Observatory, of which Cassini ...

Nonce Word
A nonce word (also called an occasionalism) is a lexeme created for a single occasion to solve an immediate problem of communication.''The Cambridge Encyclopedia of The English Language''. Ed. David Crystal. Cambridge: Cambridge University Press, 1995. Some nonce words may acquire a fixed meaning inferred from context and use, possibly even becoming an established part of the language, at which point they stop being nonce words. Some nonce words may be essentially meaningless and disposable, but they are useful for exactly that reason—the words " wug" and "blicket" for instance were invented by researchers to be used in exercises in child language testing. Lexicology The term is used because such a word is created " for the nonce" (i.e., for the time being, or this once). All nonce words are also neologisms, that is, recent or relatively new words that have not been fully accepted into mainstream or common use. The term ''nonce word'' in this sense is due to James Murray ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Astronomy
Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of prehistory: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy. It was not completely separated in Europe (see astrology and astronomy) during the Copernican Revolution starting in 1543. In some cultures, astronomical data was used for astrological prognostication. Early history Early cultures identified celestial objects with gods and spirits. They related these objects (and their movements) to phenomena such as rain, drought, seasons, and tides. It is generally believed that the first astronomers were priests, and that they understood celestial objects and events to be manifestations of the divine, hence early astronomy's connection to what is now called astrology.

Cosimo II De' Medici
Cosimo II de' Medici (12 May 1590 – 28 February 1621) was Grand Duke of Tuscany from 1609 until his death. He was the elder son of Ferdinando I de' Medici, Grand Duke of Tuscany, and Christina of Lorraine. For the majority of his twelve-year reign, he delegated the administration of Tuscany to his ministers. He is best remembered as the patron of Galileo Galilei, his childhood tutor. Biography Cosimo's father Ferdinando I took care to provide him with a modern education. Indeed, Galileo Galilei was Cosimo's tutor between 1605 and 1608. Ferdinando arranged for him to marry Archduchess Maria Maddalena of Austria, daughter of Archduke Charles II, in 1608. Their marriage was celebrated with an elaborate display on the Arno, which included a performance of the ''Argonautica'', in which Jason sailed around an artificial island and presented Maria Maddalena with six red apples, alluding to the Medici family symbolic balls, or palle. Cosimo and Maria Maddalena had eight children ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medici
The House of Medici ( , ) was an Italian banking family and political dynasty that first began to gather prominence under Cosimo de' Medici, in the Republic of Florence during the first half of the 15th century. The family originated in the Mugello region of Tuscany, and prospered gradually until it was able to fund the Medici Bank. This bank was the largest in Europe during the 15th century and facilitated the Medicis' rise to political power in Florence, although they officially remained citizens rather than monarchs until the 16th century. The Medici produced four popes of the Catholic Church—Pope Leo X (1513–1521), Pope Clement VII (1523–1534), Pope Pius IV (1559–1565) and Pope Leo XI (1605)—and two queens of France—Catherine de' Medici (1547–1559) and Marie de' Medici (1600–1610). In 1532, the family acquired the hereditary title Duke of Florence. In 1569, the duchy was elevated to the Grand Duchy of Tuscany after territorial expansion. The Medici ruled the G ...

Jupiter
Jupiter is the fifth planet from the Sun and the List of Solar System objects by size, largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, but slightly less than one-thousandth the mass of the Sun. Jupiter is the List of brightest natural objects in the sky, third brightest natural object in the Earth's night sky after the Moon and Venus, and it has been observed since Pre-history, prehistoric times. It was named after the Jupiter (mythology), Roman god Jupiter, the king of the gods. Jupiter is primarily composed of hydrogen, but helium constitutes one-quarter of its mass and one-tenth of its volume. It probably has a rocky core of heavier elements, but, like the other giant planets in the Solar System, it lacks a well-defined solid surface. The ongoing contraction of Jupiter's interior generates more heat than it receives from the Sun. Because of its rapid rotation, the planet' ...

Galilean Moons
The Galilean moons (), or Galilean satellites, are the four largest moons of Jupiter: Io, Europa, Ganymede, and Callisto. They were first seen by Galileo Galilei in December 1609 or January 1610, and recognized by him as satellites of Jupiter in March 1610. They were the first objects found to orbit a planet other than the Earth. They are among the largest objects in the Solar System with the exception of the Sun and the eight planets, with a radius larger than any of the dwarf planets. Ganymede is the largest moon in the Solar System, and is even bigger than the planet Mercury, though only around half as massive. The three inner moons— Io, Europa, and Ganymede—are in a 4:2:1 orbital resonance with each other. While the Galilean moons are spherical, all of Jupiter's much smaller remaining moons have irregular forms because of their weaker self-gravitation. The Galilean moons were observed in either 1609 or 1610 when Galileo made improvements to his telescope, which ena ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galileo Galilei
Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642) was an Italian astronomer, physicist and engineer, sometimes described as a polymath. Commonly referred to as Galileo, his name was pronounced (, ). He was born in the city of Pisa, then part of the Duchy of Florence. Galileo has been called the "father" of observational astronomy, modern physics, the scientific method, and modern science. Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and "hydrostatic balances". He invented the thermoscope and various military compasses, and used the telescope for scientific observations of celestial objects. His contributions to observational astronomy include telescopic confirmation of the phases of Venus, observation of the four largest satellites of Jupiter, observation of Saturn's rings, and a ...

Paris Observatory
The Paris Observatory (french: Observatoire de Paris ), a research institution of the Paris Sciences et Lettres University, is the foremost astronomical observatory of France, and one of the largest astronomical centers in the world. Its historic building is on the Left Bank of the Seine in central Paris, but most of the staff work on a satellite campus in Meudon, a suburb southwest of Paris. The Paris Observatory was founded in 1667. Construction was completed by the early 1670s and coincided with a major push for increased science, and the founding of the Royal Academy of Sciences. King Louis XIV's minister of finance organized a "scientific powerhouse" to increase understanding of astronomy, maritime navigation, and science in general. Through the centuries the Paris Observatory has continued in support of astronomical activities, and in the 21st century connects multiple sites and organizations, supporting astronomy and science, past and present.
